Sensitivity can be set in dosbox.conf (more details in my PM).

Ok, so it looks like sensitivity=1000, xspeed=20, yspeed=10 gives good results (apparently increasing sensitivity and decreasing the values for MOUSEX makes the motion smoother). By the way, your phrase "this Constructor game" seems to suggest you are not sufficiently familiar with it. For what it's …

Thanks! This works perfectly. Looks like I won't need to bring down my Dos PC from the attic after all. Please accept my eternal gratitude for your assistance. Doubling the x-speed gives a natural-feeling result, but I'll do some more experimentation to find out what's best.

I'm bumping this because I've encountered the same problem, and MOUSE2KV doesn't seem to work with Constructor. I don't think there's a problem with how I'm trying to use it, as it works fine with, say, Ascendancy. So - is there some way to make MOUSE2KV work with Constructor, or some other solution …

Lastly, since you were tweaking the blocksize and prebuffer before, try setting them back to default now that the game is correctly configured. The opposite worked. Now that I'm using SB, these settings effect lag in the expected way. After reducing them to blocksize=128 and prebuffer=2, the sound …

Thanks! Seeing that the sound basically worked, it never even occured to me to examine the games' sound settings. Constructor has apparently auto-detected the Gravius Ultrasound device. When I set it to SB the problem was significantly reduced (it doesn't matter which IRQ I choose for the SB, though …

Hi. This has happened to me in other games as well, but I'll take "Constructor" as an example. The problem is simple - there is a delay of about 300ms between the time a sound effect is supposed to start and the time it does. I have tried reducing the mixer blocksize and prebuffer to very low values …
